' ing is a specification.

This invention is an improvement incan` washers for rinsing and sterilizing milk cans and the like.'

`One of the principal objects of theI invention is to provide a means whereby the cream ordinarily left remaining in the milk can, after the same has been emptied, may be saved. Theinvention may be used to ad,` vantage in a Creamery or ice cream plant or As a rule in such establishments the cream or product handled is emptied from the milk cans into pasteurizers, mixers or vats, and there is left anywhere from a pint to a quart of the product remaining in thewan. The heavier the produce the more adheres to the walls of the can and remains in it. The invention I provide-will operate to remove all of the cream or product from A shaped can support 1-1 provided with a pluthe can and`h'ence efect a material saving by utilizing the product which would other-'r A further object ,of th; invention is'to provide an apparatus which may also serve as a means for rinsin and sterilizing, milk cans and like receptac es.

Another object .is ,the provision of a novelly constructed stand A'including legs, crossbars connecting the-upper ends thereof, and a pan secured to the stand by having its marginal edges coiled about the cross-bars.

Another'object ofthe invention is to proapparatus of this nature which will be exceedingly simple, `durable, efficient in operation and inexpensive to manufacture r and maintain. l 4

With these and other objects in view,`v which will become apparent as the descrip tion proceeds, theinvention resides in the construction, combination and arrangement; of parts'hereinafte'r more fully described and claimed, and illustrated in theaccompanying drawing in which like characters of reference indicate like parts throughout the several figures of which:

, Fig. 2 represents an elevational View of the can. rest and associated parts.

Fig; 3 represents a similar view of -a modified form, and Fig. 4 represents a top 'plan view of the 60 apparatus. 4 `V t Referring more particularly to the drawi ing, the apparatus includes a stand made ofv lengthsv of pipe connected by suitable fitj tings, the corner legs ofthe stand being indii I cated at 5. These legs at their upper endsare connected by the rails or members 6 on four. sides, and adjacenttheir -lower ends, on three sides by the members 7. The stand isfthus open on one side, so that a can of relatively great capacity may be placed within the stand to catch the drip from the discharge spout 8, which directs the productof the cans from the drip pan 9 into the can or receptaclewhich is placed beneath the drip pan. This drip pan 9 is made of suitable material, the edges 'of which, as indicated at 10, arer bent over the upper connecting mem' 'bers 6 of the stand, whereby tosupport the driplp'an in place on the stand, 80

Arranged above the pan 9 .is a bowlrality of openings 12 through 'which the product from the canmay-pass in reaching the drip pan 9. This can rest is mounted on a nozzle 13, in such manner that tilting movement of the rest relatively to the nozzle may be had. In. other words the .lit between Q nects the nozzle with` the inner ends of these pipes communicate.. one with a source "of water supply and the other with a sourceof steam supply. For purposes of illustration we will say that the pipe 15 is connected 100 with a sourceiof waterv supply, andthe pipe 14 with a Asteam supply. Hand operable valves 17 control 4the admission of water and steam to the, respective supply pipes. f In each of the pipes 14 and 15, is mounted 105 an automatic valve indicated by the numerals 18 and"1l9. lThese valves are ar` ranged belowthefcan rest 11, andare normally closed for cuttingfoff communication,- through thepip'es and 15,` The valves 119 supply pipes. The outer ends of the supply include stems 20, Awhich project up and tei? placed iip-side-down on the rest l1, and willA 'then be tilted to the right.

The weight of the can will unseat the valve 18 by depressing its stem 20and steam will as a consequence be injected through the nozzle 18 into the can, melting the cream or condensed milk, which melted product will run from the can through the-perforated bottom of the rest 11 .into the drip pan, and from there will pass through the spout 8 into the -receptacle below,

For rinsing a-can or similar receptacle, it would be placed on the rest 12, tilted to the left, whereby to unseat the valve 19, and 0llow Water to be injected into the can through thenozzle 13. The can would thus be thoroughly rinsed, the water 4rinning through the openings in the can rest into the drip pan and thence into a drain placed beneath the pan, or a receptacle, or onto the floor, asdesired. The can may then be tilted to the right, thus unseating the valve 18 and allowing steam to be injected into the can for sterilizing the same.

'Ilhe supply pipes '14 and 15 may be madeA of a plurality of sections of suitable form as ,indicated at Fig. 2, or may be made each of a single length of pipe bent in the shape indicated in Fig. 3, Aas found the most convenient. These pipes aresecured by clips orvother suitable fastenings 21, to opposite top rails ofthe stand. The legs -5 vof the stand at the lower ends are provided with .fianges 22 whereby the stand may be screwed to the Hoor or foundation.-

The canxrest bears upon the upper ends of the valve stems. The weight of `a can, so

long as this weight is evenly distributed on the can rest,is not suficient to unseat lboth valves. However, when the can is tilted so that its weight comes over one valve or the other,A the stein of the valve over which the weight comes will be depressed thus allowing that valve to be opened. The relatively loose .fit between the can rest and the nozzle will allow the necessary movement of the vrest relatively to the nozzle incident to theJl depression of the can rest in one direction or the other necessary toopen one valve or ythe other.

Although I have described the preferred embodiments of my invention. I may desire to make such'changes in the construction, combinationv and arrangement of parts therevof, asdo not depart from the spiritof the `fo'rated bowl disposed above said T and 4having a hole in its bottom through which said nozzle passes whereby said bowll will be tiltable, and means operated by said tilting for controlling the passage of fluid through i said pipes.
